In series, the pathogen sporangium or zoospore has to be formed followed by cyst formation, then germination of the cyst/spore to form appressorium which, enhances penetration unto host and infection vesicle, then intercellular hyphal growth and haustorium
formation and initiation of sporulation (Huitema et al., 2004; Nowicki et al., 2013).
After fruit maturation, seed germination begins, when the embryo undergoes dilation, producing a whitish mass (haustorium
), which around five months occupies the entire internal seed cavity (FREMOND et al., 1975), digesting the albumen to nourish the developing seedling.
Parasitism and haustorium
anatomy of Krameria lappacea (Dombey) Burdet & BB Simpson (Krameriaceae), an endangered medicinal plant from the Andean deserts.
With respect to the effects of bacterial cultures or filtrates on haustorium
initiation, results displayed that B.
These cells were only believed to exist in the haustorium
of the root hemiparasites but in 1984, the first report of these elements in the stem and haustorium
of aerial hemiparasitic plants was recorded .
When a dodder seedling brushes against tasty prey, a haustorium
disk forms and pushes out from the dodder stem with a fast-growing point.
Other parasitic plants tap directly into their host plants through the use of a modified root tip known as a haustorium
. The haustorium
penetrates the roots of the host plant, intertwining and interconnecting with them to absorb water and nutrients (mostly carbon).
DMBQ (10 and 20 pM), applied to Striga germilings resulting from seeds conditioned in water displayed 64 and 71 % haustorium
initiation, respectively (Table 5).
Series of laboratory and green house experiments were undertaken to investigate the effects of seed priming and salinity on germination growth of sorghum and haustorium
initiation of Striga hermonthica.
In an ecological context, epiphytism is an interaction between plants in which the epiphytic plant is dependent on the substrate supplied by the host plant (phorophyte), while obtaining nutrients directly from atmospheric moisture, without emitting haustorium
